I just put a USA Spec iPod interface into Danielle’s 2001 Jeep Grand Cherokee. I really have to start taking pictures and adding them here. Suffice it to say that there was no adapter needed in addition to the USA Spec kit. The beautiful part was that it took me all of about 20 minutes to install it and Armor All the dash before and after I replaced the stereo.  If you are looking for instructions on how to remove the stereo in a 2001 Jeep Grand Cherokee (dash removal) here you go.  It worked right out of the box. The nice part about the USA Spec kit is that it charges the iPod as well as allows you to control it with the factory CD changer controls on the factory stereo.  I put one into my Tahoe a few months ago and the installation was just as easy and works just as well in that vehicle.
